The Genus Brassavola, (L.) R.Br
The Genus Brassavola, (L.) R.Br. in W.T.Aiton, Hortus Kew. 5: 216 (1813) Type: Brassavola [B.] cucullata [bra-SAH-vo-la kyoo-kyoo-LAH-ta] There are 28 species (OrchidWiz [update Dec 2017]) that are epiphytes and sometimes lithophytes at elevations of from sea level to 3300 ft (1000 m) from Mexico, southern Caribbean islands to northern Argentina in moist or wet montane forests, mangroves, rocky crevices and cliff faces. They are most fragrant at night and many with a citrus smell. The genus is characterized by very small pencil-like pseudobulbs, often forming large clumps; a single, fleshy, apical, sub-terete leaf and the inflorescence produced form the apex of the pseudobulb. The inflorescence carries from a single to a few large flowers. The floral characteristics are elongate narrow similar sepals and petals, the base of the lip usually tightly rolled around at least a portion of the column which carries 12, sometimes eight unequal pollina with prominent opaque caudicles. The flowers usually occur, as a rule, in spring, summer and fall. The flowers are generally yellow to greenish white with a mostly white lip. It is not unusual for dark spots, usually purple, to be in the region where the sepals, petals, and lip join the stem (claw). This spotting is a dominant generic trait in Brassavola nodose. They are easily cultivated under intermediate conditions. Although this is a relatively small genus (28 species), the species show an unusually close relationship with one another in their floral patterns, coloration, and column structure making identification difficult, key to know where the plants were collected. -

Species Data Sheet Cattleya Milleri (Blumensch
Species Data Sheet Cattleya milleri (Blumensch. ex Pabst) Van den Berg, Neodiversity 3: 9 (2008) [KAT-lee-a mil-LAR-ee] Recently ‘found’, 1960, in Brazil as a miniature sized, warm to cool growing "rupicolous" lithophyte on iron ore outcroppings in Minas Gerais or on the base of Vellozia shrubs at elevations of 2500 to 4300 feet (800 to 1300 m). The clusterd red pseudobulbs are up to 2.5” (6 cm) high, widest at the base, and bear a stiff, somewhat narrow 4.0” (10 cm) ovate-oblong, keeled, rigid leaf with a sharp tip. The leaf is borne at an angle to the pseudobulb, not in line with it, and the foliage of most plants has a deep maroon flush, particularly on the backs of the leaves. The blood- or range-red starry flowers approach 2.0” (5.0 cm) in diameter, blooming in late spring and early summer (May through July) on a erect, 12 to 18" [30 to 50 cm] long, several to many flowered (approximately 6 to 12 flowers at the same time), Cattleya milleri racemose inflorescence with successive opening flowers, held well ‘Phyllis’ AM/AOS above the leaves. The lip is usually yellow with cinnabar-colored May 2010, NS 5.0 x 5.0 cm veining and varying width picotee. There are two color types, one group has narrower sepals and petals, slightly larger flowers and an orange-red color. The other group has slightly smaller flowers with wider sepals and petals and their color is a more blood-red. Synonyms: Laelia milleri Varieties / forms: None. -
ORCHID POLLINATION ECOLOGY Orchid Pollination Exploring a Fascinating World by Ron Mchatton
ORCHID POLLINATION ECOLOGY Orchid Pollination Exploring a Fascinating World BY RON MCHATTON [1] The first example of sexual deception in Australian orchids involved the genus Cryptostylis. These orchids are pollinated by male parasitic wasps of the genus Lissopimpla. Here four male Lissopimpla excelsa wasps compete for the favors of a Cryptostylis erecta flower.

In this case, pollinia of Den. infundibulum are placed on the head of the bee while that from the Cymbidium, with much longer column, becomes at- tached to the bee’s central thorax. Because the column of the former species is much shorter, only pollinia placed near the front of the bee will be in a position to contact the stigmatic surface of the Dendrobium column as the bee exits the flower (Du Puy and Cribb 2007).

Shashidhar Watch out how you take care of your Orchids!!! There is a feeling among most of the people who have gardening as a hobby that, orchids are difficult plants to grow and need lot of attention and care. Contrary to this belief, they are the easiest to grow provided you ‘listen to them’, ‘watch them’ and provide ‘what they want’. Once they are settled with your care, they live happily and make you enjoy their floral beauty. Well, I know it sounds easy, as the saying goes ‘it is easier said than done’ in most of the cases. But then, to achieve something good we have to make some efforts. Let us see some of the important parameters one has to take into account to successfully grow orchids. Before we look into these factors, give a thought about the way orchid grows in nature and what nature provides them. The whole process of growing orchids involves, trying to copy what nature provides and try to replicate the same (to the extent possible). I will start with selection of plant and move on to briefly discuss the other important factors. -

Crassulacean Acid Metabolism in Epiphytic Orchids: Current Knowledge, Future Perspectives
4 Crassulacean Acid Metabolism in Epiphytic Orchids: Current Knowledge, Future Perspectives Gilberto Barbante Kerbauy, Cassia Ayumi Takahashi, Alejandra Matiz Lopez, Aline Tiemi Matsumura, Leonardo Hamachi, Lucas Macedo Félix, Paula Natália Pereira, Luciano Freschi and Helenice Mercier São Paulo University, Brazil 1. Introduction 1.1 Crassulacean Acid Metabolism (CAM) Crassulacean Acid Metabolism (CAM) is one of three photosynthetic assimilation pathways of atmospheric CO2, together with the photosynthetic pathways C3 and C4 (Silvera et al., 2010a). The CAM is characterized by the temporal separation between CO2 fixation and its assimilation into organic compounds. In CAM plants, CO2 is fixed during the dark period through the action of the enzyme phosphoenolpyruvate carboxylase (PEPC), which uses CO2 for carboxylation of phosphoenolpyruvate (PEP), giving rise to oxaloacetate (OAA). The OAA formed is converted into malate by the action of malate dehydrogenase (MDH). Then, this organic acid is transported to the vacuole along with H+ ions, causing the typical nocturnal acidification of CAM plants. During the light period, the decarboxylation of malate and refixation of the CO2 by the enzyme ribulose bisphosphate carboxylase oxygenase (RUBISCO - C3 cycle) takes place in the cytosol, causing a decrease of acidity in the tissues (Herrera, 2009; Luttge, 2004; Silvera et al., 2010b) (Figure 1). The CAM pathway can be separated into four phases (Luttge, 2004; Osmond, 1978; Silvera et al., 2010b). Phase I is characterized by the opening of stomata during the night, the uptake and subsequent fixation of atmospheric CO2 by PEPC in the cytosol and the formation of organic acids, such as malate. Phase II consists of fixing CO2 by the enzyme RUBISCO and PEPC concurrently, a phase characterized essentially by the decrease in the activity of PEPC and the start of the activity of RUBISCO. -

Most orchids that are hummingbird- pollinated are from high- elevation ecosystems in the tropical New World where insects are rare or unable to operate because of the cold. They are particularly common in the Andean regions where hummingbirds reach their greatest diversity. Hummingbirds are found only in the Americas with at least 330 species from Alaska to the tip of South America. The greatest numbers are found in the tropics with fewer than 20 species normally found in the United States and Canada. Hummingbirds seem particularly attracted to many species of the genera Elleanthus, Cochlioda, and Comparettia. Some species of Masdevallia, Epidendrum, Encyclia, Cattleya, Sobralia, and Laelia have also adapted to hummingbirds. In addition, the highly-specialized little birds are attracted to certain species of Ada, Scaphyglottis (syn. -

Received 25 July, 2016; Accepted 21 September, 2016 Orchids are among the most beautiful flowers and endangered due to habitat destruction and over- collection. Cattleya walkeriana is one of the most beautiful flowers joining the small sized plant with medium large and heavily scented flowers. It is widely known and appreciated by its beautiful clones and it has much to offer to breeders because their plants have besides other attributes as small habit and big flowers, many colour variations, form and precocity, becoming flower only four years in ex vitro culture. However, in some of the original places it is becoming a red listed species. Notwithstanding, very little is known about the genetics of these flowers and the variability in the species that is widespread in the Brazilian territory. The aim of this work was to estimate the variability among cultivated materials using the F statistics and to verify if there was inbreeding in plant crosses with similar characteristics, employing as a tool the RAPD simple methodology. The results obtained showed that RAPD was good enough to estimate the variability in C. -
